ARRI L2.0019423 EB MAX 2500/4000Watt Electronic Ballast with ALF / CCL / DMX AutoScan - 50/60/75/300/1000Hz - Bare Ends ARR-L20019423

The ARRI L2.0019423 MAX ballast offers cutting-edge features with new remote control possibilities from 575 up to 18,000 W.

Combined with state-of-the-art ARRI daylight lampheads such as the True Blue Daylight or M-Series, the EB MAX Range enables optimal performance and advanced control for high image quality at any frame rate.

For ultimate ease of use, indicators on the ballast's front panel display the lamp wattage, DMX channel, operation mode and selected lamp frequency.

The AutoScan function provides fully automatic control of the ballast itself. After a two-stage scan the lamp frequency is selected, set, monitored and adjusted automatically by the ballast, so no futher operator interaction is required.

All models of the EB MAX Range offer new levels of DMX control. In addition to On/Off and dimming, both operation mode and frequency can now be set remotely.

The EB MAX Range accomodates high-speed frequencies at 1,000 Hz (900 - 1,200 Hz) and - in addition - at 300 Hz (270 - 360 Hz).
